Question

How can I share some data (e.g. PDF or image) from my iOS application to other apps. I mean how to invoke the modal screen when user can choose the proper app to share my data with?
I cannot find any API but I am pretty sure that it exists.

Use UIDocumentInteractionController:

UIDocumentInteractionController* docController = [[UIDocumentInteractionController alloc] init];
docController.URL = urlToFile;

Then present it

[docController presentOptionsMenuFromBarButtonItem:barBtnItem animated:YES];
